To all whom it may comer,

- citizen of the Empire-of Japan; residing at Be it known that I, WILLIAM I. KA'row, a

San Francisco, in the" county of San Francisco and State of California, have invented new and useful Improvements in Window- \Vashers,of which the following is a specification. i

This invention relates to window washing: devices and it consists in the novel features hereinafter described aud'claimed.

An object of the invention is to provide a device adapted to be applied to a window sash and having armswl'iich maybe positioned at the opposite sides of the. window pane, the said arms carrying scrubbers which may move simultaneously over the opposite surfaces of the pane thereby inaliing it possible to clean both surfaces of the pane at the same time without requiring the washer or operator to expose himself to the danger of leaning out of the window.

lVith this object'in view the device in eludes means for clamping the same in position at the lower rail of the window sash and a body pivotally connected with the said means. Arms are pivotally mounted in the body and means connect the said arms together whereby their free ends swing simultaneously toward or away from each other. The said arms are preferably made of telescoping sections. A spring actuated drum is journaled in the body and metallic tapes are arranged to wind thereon. The said tapes are guided through the arms and are attached to the scrubbing elements which are.

located at the free ends of the arms.

In the accompanying drawings Figure 1 is a side elevation of the window washer showing the same applied to the lower rail of a window sash.

Fig. 2 is a fragmentary sectional view of the same;

Fig. 3 is a side elevation of one scrubber used upon the washer Fig. 4 is an edge elevation of the other scrubber used upon the washer.

The window washer comprises a body 1 formed preferably from sheet metal and of any desired configuration. The said body. is-provided at one end with an eye 2 which may receive a nail or hook whereby the body may be hung up when the device is not in use. Extensions 3 of arms hereinafter described are pivotaliy mounted in the body 1. at the opposite end portions thereof and a in sections 7.

disks: is journaled in the intermediate portion of the said body." Rods 5 are pivotally connected at their inner nds withtlie side of'the disk 4 at the opposite sides of. the

center thereof and pivotally connected at their outer ends to the upper extensions 3..

The arrangement ofthesaid rodsand-disk swung upon its pivot in an inward direc-- tion the other/extension swings-correspondingly and also the upper ends-of the said extension may swing simultaneously in outward directions, Hollow arms 6 are carried by the extensions 3 and :the .said arms arepreferably composed of telescop- A spring actuated drum 8.is journaled for rotation in the intermediateportion of the body 1 and metallic tapes 9' are arranged to Wind upon the periphery of the said drum. Rollers 10'are journaled for rotation'at the lower portions of the brackets 3 and the intermediate portions'o'f the tapes 9 are trained under the said rollers. The end-portions of the tapes 9 are extended through the arms 6 and are attached to scrubbers hereinafter described. Rollers 11 are also journaled in the body 1 and serve as means for properly guiding or directing the tapes to the rollers 10. A fiat strip 12 is slidably mounted in the end section of that arm 6 which is intended tobe inner surface of the window pane andthe L said scrubber 14 need not necessarily be made flat or thin. v

Bars 15 are pivotally connected with the upper portion of the body 1 and are adapted tolie alonetheopposite surfaces oi the lower-rail of the window sash. The bars 15 carry at their upper ends journaled rollers 16 which are intended to extend'over the upper edge of the lower rail of the sash. A clamping member 17 is connected with the intermediate portion of the bars 15 and a clamping screw 18 is threaded through one end of the member 17. A clamping plate 19 is carried at the innerend. of the screw 18 and is adapted to cooperate with r the clamp member 17 in holding the device 1n position upon the sash of a window.

In operation, the bars 15 are placed along the oppositesurfaces of the lowerrailof a window sash and the rollers 16 are engaged over the upper edge'thereof; The

bars may be moved along the said .rail until they are at'a desired position when the clamping screw is tightened and thus the sash rail is gripped between the clamp 7 member 17 and the plate 19. An operator grasps the scrubber 14 and may swing the same along the inner surface of the window pane. During the swinging movement the body rocks upon its pivotal connection with a the bars 15, consequently the arms -6 at the opposite sides of the window pane sv'vmg simultaneously in the same direction. As the upper end of the arm 6 at the inner side of the Window pane is moved away from the same, the upper end of the arm 6 at the outer side'thereof moves correspondingly through the connections 4 and 5 hereinbefore described. As the scrubber 14 is moved up or down-alongthe window pane the tape 9 which is connected with the said scrubber winds upon or unwinds from the drum 8 and the tape which is connected with the scrubber at the outer side of the window pane moves correspondingly, consequently the twoscrubbers are "alwaysopposite each other and against the .opposite surfaces of Y the window pane. The tapes 9 are of metal be manipulated inorder to clean both surfaces of the pane at the .s'ame'tim'e and without requiring the operator to leanout of the window.

- Having described theinvention what is claimed is:- y

A window washer comprising a body, 1on-. gitudinally extensible arms'pivoted at one end thereon, scrubbers carried at the 'free ends of the arms, means for causing thev arms to swing simultaneously toward or away from 'each other, a spring actuated drum journaled in the body, tapes arranged to wind upon the drum and trained through the arms and connected with the arms at the free end portions thereof.

In testimony ture.
